Electrical question

[Kc1983]

I own a 2022 crossroads volante 28BH.

I recently had a 30 amp outlet installed at the house so that I could run the AC while parked at home.

When the outlet was installed it was accidentally done with 240 instead of 120. Unfortunately, this was realized after we plugged in the camper in and tried opening the slide.

The plug was then rewired for 120.

Now, we can't get anything in the RV to work on shore power, except the microwave.

When it runs on the battery everything works.

Any ideas???

Sorry I meant 220 instead of 110. I don't know how to edit posts.

Plugging a trailer into 220 is generally deadly for all 110-volt items (TV, Air conditioner, etc.) but may not impact the 12-volt items. Generally the slides, leveling system, inside lights, etc. are 12 volt.

I don't understand the microwave still working, and while I haven't experienced this issue myself, I've been reading these forums for many years and historically 220 instead of 110 is a very bad thing.

Maybe someone much more experienced with electricity than me can advise you further.

I presume you did check all fuses and circuit breakers inside the trailer?

Hopefully your trailer is insured.

All of the fuses and breakers are fine. When I hook up the trailer to my truck I can power the slide and all of the lights will turn on.

Could it be the converter? Is it possible that there's another circuit box hidden somewhere in the RV? Trailer is insured.

When hooked up to your truck you are using the truck battery to power the 12 volt system showing that it is working. So on shore power check the battery disconnect to be sure it is on. Your converter more than likely is toast but the camper battery should still provide 12 volt. If you have a meter check at the camper battery for 12 volts while unplugged from the truck and shore power. Your battery may be dead.

On the 110 volt side you will just have to turn on everything to see what still works and what does not. The breaker may have tripped before the microwave was damaged but I would still check its functions to be sure.

Good luck and let us know how it goes.

That happened to me once in a storage lot. The guy before me had a 220 volt window unit plugged in and had rewired the receptacle. You likely have lost your inverter, microwave and any other 120 volt items you had turned on.
Your electrician should have known better. I would be talking to him about reimbursement.

If you can run a 110 extension cord to the trailer use it to plug the 110 items into to see if they work, but they may have fried. You will need a new inverter and they aren't that hard to install, but I agree that if you told the electrician what it was for, he should have wired it 110. I would contact him and if he is licensed (should be) he should also be bonded and insured for such damage and will hopefully work with you to replace the damaged items. Including the inverter.

Looks like you drove 220v direct to the inverter, which is the brain center for your 110v system. I have never had any dealings with the inverter and not sure if it is equipped with it's own breaker in case of a power surge. If that is the case if you can find that breaker, which is probably right on the unit that may help.

Not sure how the microwave survived that when everything else does not work. Did you smell any burn wire inside the trailer? Something may have melted with that much juice going to it.

Do you have a 110v 30amp working now on your hook-up for the trailer? Disconnect your trailer battery and check to see if you are getting a reading from the inverter. This may give you some indication that the inverter is working in some capacity.

Find out how to check your inverter to see if any power is going in and what is coming out. This will tell you if it needs replacing.

You may possibly had an inline surge protector. Look in the small door where you store your power cable and see if there is a long yellow box. If yes it’s fried but everything else will most likely be ok. In the event you do not have this your power inverter is going to be fried and most likely all the 110 volt breakers. I seriously doubt any of your appliances are hurt. I am a master electrician and like everyone is saying if this guy was a real electrician he is responsible. I seriously doubt he’s a real electrician. Some other great advice is once it’s repaired make positively sure you install an inline surge protector. In the event you have a power surge it protects everything in the RV. What is your location? If you are anywhere close to me I would be happy to repair it for you.

There's no such thing as 110V and 220V in the Canadian or US power grid and hasn't been for many decades. The correct voltages are 120/240V

You are 100% correct. But 99% of the people say 110 & 220. But an electrician knows exactly what they mean.

First, you are confusing the convertor with an invertor
They are entirely different. devices.
Second. You have no idea if the convertor is bad, based on the OPs information.

[Yakherder]

Well, there has been lots of input on 110/120, 220/240 and testing 12vdc etc.

Does anyone know how to test the converter to see it it is toast. I have never dug around in mine to see what makes it tick or to see if there was a power surge protector device on it.

I would like to know this information and possibly it will help KC1983 find the solution to their problem.
